Answer:
28.26
Step-by-step explanation:
The formula for calculating diameter is π<em>d</em> (pi times the diameter), so 3.14 times 9 is 28.26.
42-14= 28
28÷2=14
answer: there are 14 females in the class and 28 males in the class
Check:14+28=42
Recall your d = rt, distance = rate * time
thus

notice, the first car leaves at "x" time, the other leaves on hour later, or x + 1
the first car travels some distance "d", whatever that is, thus
the second car, picks up the slack, or the difference, they're 380 miles
apart, thus the difference is 380-d
Answer:
The y-intercept point would be on the -5 of the y-axis while the x-intercept would be on the -5 of the x-axis.
hope this helps :)
